Abstract
We report an 89-year-old man who presented with a slowly growing pigmented pedunculated tumor. The nodule was diagnosed as a spindle cell pedunculated malignant melanoma (PMM), a rare variant of spindle-cell malignant melanoma. The clinical presentation of this tumor and its histological and immunohistological features are discussed.
